Type material.

Holotype, ♀ (OPU), "[China:] Formosa, Nokosan, V.1922, M. Kato", "Holotype Orthogonalos formosana   Ter., ♀".

Diagnosis.

Vertex with large yellow patch medio-posteriorly (Fig. 222); head dorsally and mesoscutum coarsely punctate (Figs 222, 226); mesosoma laterally with extensive pale yellow or ivory pattern (Fig. 227); posterior half of propodeum obliquely rugose (Fig. 227); spiracle of propodeum distinctly protruding (Fig. 227); vein 1m-cu of fore wing connected to first submarginal cell (Fig. 224); legs mainly yellowish brown, including outer side of hind coxa (except base) but hind tibia (except basal quarter) and tarsus dark brown (Fig. 230); first tergite robust and with median groove, its apical half of first tergite entirely pale yellowish (both sexes; Fig. 228); medially third sternite half as long as second sternite.

Description.

Holotype, ♀, length of body 9.0 mm (of fore wing 8.3 mm).

Head. Antenna incomplete, with 26 segments according to original description; frons and vertex coarsely punctate and partly with smooth interspaces equal to width of punctures or wider; temple smooth; head subparallel-sided behind eyes, eye in dorsal view 1.1 times as long as temple (Fig. 222); occipital carina narrow, non-lamelliform and smooth dorsally (Fig. 222); supra-antennal elevations medium-sized (about 0.5 times as long as scapus), outer side oblique and punctate, apically smooth and non-lamelliform (Fig. 222); clypeus nearly straight and thick medio-ventrally.

Mesosoma. Length of mesosoma 1.3 times its height (Fig. 227); postero-dorsal corner of pronotal side protruding far posteriorly (Fig. 227); mesopleuron below transverse mesopleural groove distinctly punctate with smooth interspaces about equal to diameter of punctures, above groove densely punctate and partly with rugae; transverse mesopleural groove anteriorly wide, deep and coarsely crenulate, narrow and finely crenulate posteriorly; notauli wide, deep and coarsely crenulate; mesoscutum coarsely punctate with wide smooth interspaces, lateral lobes with a narrow mid-longitudinal furrow (Fig. 226); scutellar sulcus wide and coarsely crenulate; scutellum mainly smooth except some punctures, rather convex and anteriorly above level of scutellum (Fig. 226); metanotum medially moderately convex and protruding, smooth (Fig. 226); propodeum irregularly reticulate-rugose, posteriorly partly smooth and median carina nearly complete (Fig. 226); posterior propodeal carina weakly developed and non-lamelliform and distinctly arched, foramen medially about as high as wide basally.

Wings. Fore wing: length of vein 1-M 2.7 times as long as vein 1-SR (Fig. 224); second submarginal cell 1.6 times longer than third cell.

Metasoma. First tergite 0.4 times as long as apically wide, smooth and with linear depression medially (Fig. 228); other tergites and sternites smooth to superficially coriaceous and shiny (Fig. 228); third sternite half as long as second sternite (Fig. 229); hypopygium truncate in ventral view.

Colour. Black; mandible, clypeus, face, curved patch behind eye dorsally, triangular patch behind stemmaticum, ventral half of outer orbita and inner orbita largely and widely, large posterior patch on middle lobe of mesoscutum and on scutellum, metanotum medially, large patches on propodeum medio-posteriorly and laterally, pronotal side dorsally and ventrally, two large patches on mesopleuron and large patch on metapleuron, first metasomal tergite and sternite largely, second tergite laterally, second sternite largely, second–fourth tergites latero-posteriorly, fifth and sixth tergites posteriorly, seventh tergite, third–fifth sternites laterally, pale yellow or ivory; remainder of metasoma dark brown; antenna black with a wide ivory band (apex of 10th and 12 th– 19th segments) subapically and scapus and pedicellus largely dark brown; fore leg missing; middle and hind legs brownish-yellow, but coxae narrowly basally, hind tibia (except basally) and hind tarsus dark brown; pterostigma and veins dark brown; wing membrane subhyaline.
